The board mandates that Office of Evaluation and Oversight (OVE) conduct Country Program Evaluations (CPE); policy, strategy, thematic and instrument evaluations; and oversee the bank's internal monitoring and evaluation system, processes and instruments. Moreover, OVE conducts oversight reviews of corporate strategy, processes and instruments; provides normative guidance on evaluation issues; and contributes to evaluation capacity building in the region. In 2003, OVE began conducting ex-post project evaluations as well. Self-evaluations are carried out by programme staff in operational departments.

OVE carries out evaluations of development impact, ex-post performance and sustainability of individual projects classified into three themes: country programme evaluations whenever there is a national election; sector and thematic evaluations; oversight reports on bank policies and programmes.

Each profile provides information on the core elements of the evaluation function set-up and management, including the mandate of the unit, mechanisms to protect independence and ensure quality, reporting lines and distribution of evaluation reports.
